This, to me, is an obscure species. In D onn' s Cata- 

 logue it is said to be a native of South-America. QL. fiarviflora, 

 of the Catalogue of New-York Plants, I am now convinced, is 

 a variety of Qi. biennis.

Root biennial. Stem 3 — 3 feet high, terete, a little hairy, much 

 branched above. Leaves ovate-lanceolate, subdentate, pubes- 

 cent. Tube of the calijx very long ; segments of the border 

 united, except at the base and apex, split by the expansion of 

 the flower, and turned to one side. Corolla 2 — 3 inches in 

 diameter, yellow ; petals roundish. S(a?nens shorter than the 

 corolla, slightly declinate. Cafisiile subquadrangular, an 

 inch and a half long, 4-toothed at the summit. Seeds angular. 



Hab. In fields, and along the borders of woods. New-Jersey 

 and Pennsylvania. July — August. 



Is this more than a variety of Qi. biennis ?
